K3MA-F Frequency/Rate Meter

Highly Visible LCD Display

LCD with Backlight Provides Excellent Visibility

Characters are easy to read even in brightly lit places.

Totally Programmable Display Colors

The display can be programmed to change colors.
For example, it can be set to display in green normally, and in red for errors; or to change from either green to red or red to green when output turns ON; or to display only in one color, red or green.

Bright, Changeable Red and Green Display Colors Show Conditions at a Glance

The measurement display can be set to change colors according to 

the comparative output, to show conditions even at a distance.

Settings are easy to make, with front-panel key operation

Digital processing simplifies adjustment and setting operations. There is no need to apply actual input signals.

NEMA4X (IP66 equivalent) water- and dust-proof structure

The front panel is washable and can be handled with wet hands, making it highly suitable, for example, for use in food processing and in other systems requiring water.

Front Panel Features

Scaling

This feature converts input signals into desired physical values.

For example, a pressure sensor is connected in which a current range of 4 to 20 mA corresponds to a pressure range of 0 to 100 kPa. The readout for the input of 4mA is converted into "0" and that for the input of 20 mA is converted into "100" (kPa). Since scaling converts the input signal from a value of current into a unit (kPa) that is used in the system, it enables easier, intuitive understanding.

Comparative Output

This feature compares a scaled value (measurement value) with a programmed OUT set value and performs an output action according to the comparison result. This is useful in monitoring various systems for malfunction or determining whether products are acceptable.

Three types of comparative outputs are available: those produced at the OUT upper-limit value, the OUT lower-limit value, and both the OUT values.

Forced-zero

This feature shifts a process value to zero. Forced-zero can be used to evaluate and display the deviation of a process value from a reference value.
